This study pointed to the assessment of the chemical composition (F, Ca, Mg, Na, K, Fe, Mn, Zn, Cu, Ni, Co, Cr, Cd, and carbohydrate) of different marine seaweeds (red, green, and brown) from the Egyptian Mediterranean Sea coast. The results showed that green seaweeds supplied better calcium sources than the red and brown ones. Also, red and brown seaweeds showed higher averages of Na and K tha...

This study was envisaged to explore the impact of pesticide solid waste leachate to Allium cepa (common onion) bulbs. Bulbs exposed to the leachate showed hampered root growth and morphological deformities. At 15% and higher concentrations of leachate after 5 days, gall like swellings were noticed around the mitotic zone (zone of root growth). From the dose response curve, the EC50 values for t...

The purposes of this study were to assess the hair mercury concentration of women of childbearing age in Taiwan, and to calculate a hazard quotient (HQ) to evaluate the risk of fish consumption for these women. We also examined perceptions of risk associated with fish consumption and whether women in our study changed their habits in response to such risks. The average concentration of mercury ...

In this study, soil samples were collected from a large-scale open-cast coal mine area in Inner Mongolia, China. Arsenic (As), cadmium (Cd), beryllium (Be) and nickel (Ni) in soil samples were detected using novel collision/reaction cell technology (CCT) with inductively-coupled plasma mass spectrometry (ICP-MS; collectively ICP-CCT-MS) after closed-vessel microwave digestion. Human health risk...

Heavy metal pollution in soils caused by mining and smelting has attracted worldwide attention for its potential health risks to residents. This paper studies the concentrations and accumulations of Sb and As in both soils and vegetables and the human health risks of Sb and As in vegetables from Xikuangshan (XKS) Sb mine, Hunan, China. Results showed that the soils were severely polluted by Sb ...

The hazard of adverse effects to aquatic organisms arising from groundwater contaminated with a complex mixture of volatile chlorinated hydrocarbons (CHCs) discharging to Penrhyn Estuary, Sydney, Australia was determined using the hazard quotient (HQ) method. The hazard posed by 14 volatile CHCs acting individually and collectively as a mixture was assessed. The hazard was determined using meas...

Monitoring the quality of surface water is an important step towards sustainability resources. Quantum Geographic Information System (QGIS) opensource desktop application which used for editing and analysing geospatial data. This study aims to develop a QGIS plugin named Lake Ecosystem Tool monitor health condition lake in terms index, trophic state hazard quotient, aerial spread volumetric cha...

Introduction: In recent years, the contamination of food with heavy metals has received much attention. Plants can absorb metal pollutants through contaminated water, soil, and air. Materials and Methods: In the current study, accumulation of minerals in three types of soybeans was investigated by wet and dry digestion methods using ICP-OES technique. Thereafter, the metals' health risk was as...

Volcanic eruptions disturb directly and indirectly the ecosystems. Direct impact occurs on soil–plant system with an input of new elements indirect hazard by consumption these plants. Fogo island (Cape Verde Republic) has active volcano last eruption occurred in 2014–15, expelling large amounts materials that spread all over island. Soils edible plants were collected Pollution indexes reveal co...
